IMPROVEMENT IN PENCIL-CASES.

The Schedule referred to in thse Letters Patent and making part oi thesame To whom. it Imay concern:

Be it known that I, WILLIAM N. BAnrHoLoMnw, of Newton Centre, county ofMiddlesex and State of Massachusetts, have invented a new and ImprovedCombinedPoint-Protector, Extension-Piece, and Lead- Iencil, of which thefollowing is a specification.

Considerable inconvenience is experienced in carrying the ordinarylead-pencil in the pocket. If the pencil be of the usual length itis aptto be in the way, andA to project from the pocket, if it be shortened itcannot be conveniently held in the hand and used for any length oi'time, and atl all times the lead point is not only liable to be broken,but also to tear or otherwise injure the pocket.

The object ot' my invention is to remedy these difficulties, .and tothis end I combine with a pencil of suitable length, considerablyshorter than the ordinary lead-pencil, a tubular stem of metal or othermaterial in which the pencil is inserted, and which will form either anextension piece or a point-protector, as desired. The pencil to be usedwith this tubular stem is formed s0 as to have a double taper, that is,to taper toward bot-h ends, so that either end ot the pencil wheninserted in the stem may be wedged and held securely therein.

The manner-iu which my invention is or may be carried into effect willbe readily understood by refererence to the accompanying drawings.

Figures 1, 2, 3, 4 represent central longitudinal sections of the penciland tubular stem made vin accordance with my invention.

In gs. l and 2` the double taper to the pencil is formed on the woodensheath. The greatest diameter of the sheath `is at a point, a, quitenear the head or that cud of the pencil which-is not intended to besharpened, and the pencil tapers thence in vboth directions, thusproducing a double tapered head.`

The short tapered portion between a andb is. intended to be inserted inthe tubular stem (l when the pencil is required for nseasa shown in fig.1, in which position the combined length` of the pencil and stem isquite equal to thatof an ordinal)T pencil, and suficient to allow thepencil to be easily held between the fingers and supported by the hand.

The longer tapered portion between a, and c is intended to be insertedin thestem when the pencil is no longer required for use, as seen in g;2, in which position the pencil is of but little length, being receivedforthe most part in the tubular stem, which now, instead of forming anextension piece, becomes .a point-protectorl v The tubular stem has aninternal diameter about equal to the diameter of the pencil at a., sothat theand held tightly iu the tubular stem whichever end be insertedtherein.

It will be understood that it is by no means neces` sary that the pencilshould taper continuously between (c and l) and a and c; on thecontrary, only such portion of the pencil need be tapered between thesepoints to produce a double incline or taperv to tit and wedge in thetube, while the other parts oi' the pencil may be cylindrical or otherordinary shape.

In figs. 3 and 4 the `double taper is formed not upon the sheath itself,but upon a head, h, of bone, India rubber, or other material, attachedto one end of the pencilin any suitable manner, either tting upon atenon, as seen in iig. 3, or being screwed upon the pencil end, as seenin g'. 4. The body of the pencil in this case is of the usualcylindrical or polygonal form. v

Instead of using a separate head, h, one end of the wooden sheath may bemade in the same form, and to answer the same purpose as the head, as Ihave already indicated.

From the foregoing it Will be seen that all that is needed to adapt thepencil for use with theextension and protecting-tube, is that it shouldbe slightly bulging near one end so as to form what I have termed thedouble taper, by which the pencil can be firmly held to the tube,whether the point be inserted in the tube for the purpose of protectionor withdrawn therefrom and turned outward for use in writing, &c.

Having now described my invention and the mauner iu which the same iusor may be carried into effect,

What I cla-im, and desire to secure by Letters Patent, is

1. A combined point-protector, extension piece, and lead-pencilconsist-ing of an extension and point-protecting tube in a combinationwith a lead-pencil furnished at or near one end with a double tapered oriuclined head adapted to be wedged and held in the tube Whether thepoint ot the pencil be turned out from or inserted in said tube,substantially as shown and set forth. v

2. A lead-pencil, the wooden sheath of which is formed with a doubletaper, so as to admit of the same being wedged and held in the extensionand protecting-tube in which either end of the pencil may be inserted,substantially asdescribed. In testimony whereof I have signed my name tothis specification before two subscribing Witnesses.
